The Siena is designed around one idea – sophisticated comfort. The contoured seats have 45 powerful jets, including the 14-jet turbo massage that targets the lower back. The jets are powered by two 4.2 HP BT (2.5 Continuous Duty) Hi-flow energy pumps. This spa utilizes an Econo-Boost heat recovery system, saving money and valuable natural resources. This recovery system helps the spa use as little energy as possible; far exceeding the California Energy Compliance mandate. Built with quality, the spa shell is manufactured with Lucite-Xtra Acrylic and a 3 layer strengthening process called Dura-Bond. The cabinet is constructed of synthetic wood panels that require no maintenance. The panels are reversible; if one side gets damaged over time, simply remove the panel, flip it over, and reinstall it into the cabinet. Dura Frame, a patented galvanized steel frame support system, provides significant durability and longevity for the spa.

Quality Components

Tastefully designed with a DuraFrame® maintenance free cabinet, this spa will compliment any decor and is engineered to perform efficiently all year long. The cabinet frame is constructed of galvanized, powder-coated steel for long lasting durability. The cabinet panels are reversible and easy to remove to keep the spa looking new. The jets are powered by energy efficient hi-flow pumps, with an air flow control system to add air to the jets for an invigorating spa experience. The Dura-Bond™ four layer strengthening process combines high density material that is reinforced with a fibrous chop that yields superior strength to the spa shell. The Dura-Bond™ strengthening system produces no VOC’s (Volatile Organic Compounds); a harmful emission that can affect the environment and human health. Maintenance is made easy with automatic filter cycles, automatic heating systems, and automatic freeze protection.

Total Control

Operation is easy with the top side electronic controls that you can access from inside or outside the spa. Balboa digital electronic topside control for ultimate reliability. A four-button Soft Touch™ control for pump, temperature, and light. The Soft Touch™ pad also features LED temperature diagnostic read-outs.

Go Green: Energy Saver System

All of our spas feature an Energy Saver System. This frictional heat recovery system uses the heat generated by the action of the pump and motor to heat your spa. This recycled heat is not vented away as in other spas, but trapped in the dead air space of the cabinet to assist in warming the spa shell and water. This saves valuable resources and money. Our 4KW heaters also feature M-7 technology, self protecting from overheating in all weather conditions.
